    @wxheader{sysopt.h}

    wxSystemOptions stores option/value pairs that wxWidgets itself or
    applications can use to alter behaviour at run-time. It can be
    used to optimize behaviour that doesn't deserve a distinct API,
    but is still important to be able to configure.

    These options are currently recognised by wxWidgets.
